Hey all -

I have a use case where I need to query for a substring or regex pattern from a field, then visualize it in Kibana.

I have a field called "description" in an index, in which various data is stored. The data follows this pattern:

`application_name - metric : value`

`application_name`, `metric`, and `value` can all vary depending on the source of the data, so what I want to do is pull out `application_name`, then build a vertical bar chart showing the Count of different `application_name` values we receive. So for instance:

`application_name1` = 30 events last 24 hours  
`application_name2` = 72 events last 24 hours  
`application_name3` = 13 events last 24 hours

Unfortunately I don't have a way to change the source, otherwise I would split up the data into individual fields and that would make things a lot easier.

Is this feasible?

Hi @sdberts,

Have you tried to extract application name in a dedicated [scripted field](https://www.elastic.co/guide/en/kibana/current/scripted-fields.html)? Then you can apply any aggregations (incl. count) on this new field.

Best, Oleg
